Do you mean on a large scale? The only examples of people purposely converting energy to mass are small scale physics experiments.

Some details on electron-positron pair production can be found here: http://en.wikipedia.org/wiki/Pair_production.

To transform energy in mass one needs to create a particle and it's antiparticle from energy...then separate them before they recombine...Al68 posted the only 'observed' example I know.

In theory, Hawking radiation results from particle/antiparticle production...you can read about that in Wikipedia for an explanation...essentially an intense gravitational field separates the pair and we observe one as real and the other "disappears" beyond an event horizon..."we" don't have experimental proof of that and certainy don't know how to do it ourselves.

Hi Naty1 What I got from the article was there have not been actual photon-photon creations of particle anti particles observed but I am not to sure of my reading. DO you know have these actually occurred in cloud chambers?

Austin: I'm not sure what you are asking and I'm not good on particle interactions either...but if you are asking can photon pairs be created from matter the answer is definitely yes:

and I'm guessing that has been observed many times.
